Estágio em clínica de animais de companhia: síndrome de disfunção cognitiva canina

Este estágio foi realizado em clínica de animais de companhia. Observou e acompanhou-se tanto consultas com carácter preventivo como de clínica médica e cirúrgica. As consultas de medicina preventiva consistiram essencialmente em vacinações e desparasitações, enquanto outras foram meramente informativas. As consultas de clínica médica incidiram em diversas áreas, incluíndo dermatologia, gastroenterologia e cardiologia. As cirurgias efetuadas foram sobretudo eletivas, mas também se assistiu a cirurgias corretivas. Um dos casos observados foi um cão com disfunção cognitiva. Este foi o caso escolhido para ser alvo do estudo mais aprofundado que é apresentado na segunda secção deste relatório. A disfunção cognitiva canina é o equivalente à doença humana de Alzheimer. Esta condição é relativamente desconhecida e os seus sinais clínicos são frequentemente considerados normais da idade. No entanto, quando detetada e tratada atempadamente é possível abrandar a sua evolução, devendo os proprietários de cães afetados ser sensibilizados a procurar assistência profissional; Internship in small animal practice: canine cognitive dysfunction syndrome Abstract: This internship was conducted in small animal clinic. The attended appointments consisted mostly of cases of preventive and internal medicine and also surgical assistance. The appointments of preventive medicine included vaccinations, deworming and some merely informative sessions. The cases of internal medicine concerned areas such as dermatology, gastroenterology and cardiology. The surgical interventions were mainly optional but also corrective procedures. One of the observed cases was a dog with cognitive dysfunction. This case was elected to be the target of further study which is presented in the second section of this report. The canine cognitive dysfunction is the equivalent to the human Alzheimer’s disease. This condition is still largely unknown and its clinical presentation is often considered normal of aging. However, if detected and treated early it is possible to slow down its progress, thus the owners of affected dogs should be encouraged to seek professional assistance.

Assessment of the genetic diversity of the pinewood nematode, Bursaphelenchus xylophilus, in Portugal

O nemátode da madeira do pinheiro (NMP), Bursaphelenchus xylophiius, tem uma extensa distribuição na América do Norte, e encontra-se atualmente distribuído ao longo da maioria dos territórios de Canadá e dos Estados Unidos. Durante o último século, esta espécie foi transportada pelo Homem para outras regiões do mundo (não-nativas), associadas com o comércio e o fluxo global de produtos de origem florestal. Atualmente, esta espécie invasiva está reportada para algumas regiões do SE asiático (China, Japão, Coreia e Taiwan) e mais recentemente para a Europa (Portugal). Devido ao impacto que este organismo agente da doença da murchidão dos pinheiros causa nas florestas nativas destas regiões esta espécie assume uma elevada importância económica a nível mundial Em Portugal, a distribuição do NMP encontra-se confinada a uma área restrita e limitada (500 000 ha), a sul de Lisboa (península de Setúbal); contudo, constitui uma das maiores ameaças às florestas de pinheiro do país e da UE. Ate recentemente, nenhum consenso existia quanto à origem do NMP em Portugal. Diversas hipóteses têm sido colocadas para explicar esta introdução, nomeadamente a partir de zonas onde o nematode ocorre naturalmente (América do Norte), ou de outras áreas (não-nativas) onde o nematode se comporta como uma espécie invasiva (Leste da Ásia). A fim de avaliar a variabilidade genética do NMP proveniente da área afetada em Portugal, foram utilizadas várias técnicas moleculares, designadamente o random amplified polymorphic DNA (RAPD-PCR) e o satellite DNA (satDNA). No caso do RAPD-PCR, foram utilizados 24 isolados do NMP provenientes de Portugal, 1 proveniente da América do Norte e 1 da Ásia, tendo sido utilizado como out-group um isolado de B. mucronatus. A partir dos 28 RAPD primers utilizados obtiveram-se 640 fragmentos. No caso do satDNA, foram utilizados 21 isolados do NMP provenientes de Portugal, obtendo-se no total 206 sequências da família MspI. Ambos os métodos revelaram uma elevada similaridade genética entre os vários isolados do NMP da área afetada em Portugal O nível reduzido de diversidade genética obtido entre os isolados portugueses do NMP, permite concluir que se trata de uma única introdução deste organismo em Portugal, e proveniente de uma região asiática. A inexistência de uma de correlação entre a variabilidade genética e a distribuição geográfica do NMP dentro da área afetada em Portugal, indica que o NMP se encontra distribuído de forma uniforme ao longo de toda a área afetada, provavelmente relacionado com a distribuição e a expansão natural do inseto vector. The pinewood nematode (PWN), Bursaphelenchus xylophilus, has a wide distribution in North America, and is present throughout most of the territories of Canada and the United Stata. During the last century, this species has been transported by man to several non-native regions of the world, associated with trade and the global flow of forest products. Up to date, this invasive species has been reported from Asia (PR China, Japan, Korea and Taiwan) and more recently in Europe (Portugal). Due to the impact on native pine forests of these regions, this nematode species, the causal agent of pine wilt disease, is of great economic importance worldwide. In Portugal, the distribution of the PWN has been constrained to a relatively small area (500 000 ha) in the south of Lisbon (Setúbal Peninsula); however, it has become the most serious threat to pine forests in the country. Until recently, no consensus had emerged on the possible pathway of the PWN introduction in Portugal. Several hypotheses have been put forward to explain this introduction, such as an origin from endemic areas where the nematode naturally occurs (North America), or non-endemic areas where the nematode behaves as an exotic pest (East Asia). Random amplified polymorphic DNA (RAPD-PCR) and satellite DNA (satDNA) techniques were used in order to assess the level of genetic variability and genetic relationships, among several isolates of the PWN, representative of the entire affected area in Portugal. In the case of RAPD-PCR, 24 Portuguese isolates, plus two additional isolates of B. xylophilus, representing North America and East Asia were included. B. mucronatus was used as an out-group. Twenty-eight random primers generated a total of 640 DNA fragments. With satDNA, 206 Mspl sequence repeats were obtained from 21 Portuguese isolates of B. xylophilus. Both molecular methods revealed a high genetic similarity among the Portuguese isolates, and the low level of genetic diversity strongly suggests that they were dispersed recently from a single introduction, and from East Asia. The lack of apparent relationship between the genetic variability and the geographic distribution of the PWN within the affected area, suggests that the recent introduction of this pest (and pathogen) in Portugal has been uniformly distributed since its establishment, probably following the natural distribution and expansion of the insect vector.

Sex-related invariance across cultures in an online role-playing game

This study examines the Social Dominance Orientation of players of the online roleplaying game World of Warcraft. The World of Warcraft offers an opportunity to investigate social dominance and biological sex differences in an environment where there is no cultural dominance of one sex over another. Social Dominance Orientation has been found to be different between males and females, with males scoring higher. However, this might be the consequence of social context. To this end sex differences between male and female players were investigated in the World of Warcraft environment, as well as the effects of chosen character sex. Player sex and character sex were found to have effects on Social Dominance Orientation. These results add further support to claims that Social Dominance Orientation has the characteristics of a sexually selected disposition to acquire resources and out-compete rival groups.

Multi-scale lines and edges in V1 and beyond: brightness, object categorization and recognition, and consciousness

In this paper we present an improved model for line and edge detection in cortical area V1. This model is based on responses of simple and complex cells, and it is multi-scale with no free parameters. We illustrate the use of the multi-scale line/edge representation in different processes: visual reconstruction or brightness perception, automatic scale selection and object segregation. A two-level object categorization scenario is tested in which pre-categorization is based on coarse scales only and final categorization on coarse plus fine scales. We also present a multi-scale object and face recognition model. Processing schemes are discussed in the framework of a complete cortical architecture. The fact that brightness perception and object recognition may be based on the same symbolic image representation is an indication that the entire (visual) cortex is involved in consciousness.

Object segregation and local gist vision using low-level geometry

Multi-scale representations of lines, edges and keypoints on the basis of simple, complex and end-stopped cells can be used for object categorisation and recognition (Rodrigues and du Buf, 2009 BioSystems 95 206-226). These representations are complemented by saliency maps of colour, texture, disparity and motion information, which also serve to model extremely fast gist vision in parallel with object segregation. We present a low-level geometry model based on a single type of self-adjusting grouping cell, with a circular array of dendrites connected to edge cells located at several angles.

Approaching Models of Nursing from a Postmodernist Perspective

This paper explores some questions about the use of models of nursing. These questions make various assumptions about the nature of models of nursing, in general and in particular. Underlying these assumptions are various philosophical positions which are explored through an introduction to postmodernist approaches in philosophical criticism. To illustrate these approaches, a critique of the Roper et al. model is developed, and more general attitudes towards models of nursing are examined. It is suggested that postmodernism offers a challenge to many of the assumptions implicit in models of nursing, and that a greater awareness of these assumptions should lead to nursing care being better informed where such models are in use.

Counselling Psychology in the United Kingdom

Counselling psychology within the UK has grown over the last three decades, adapting to many changes in the field of applied psychology, whilst remaining true to its core values and humanistic origins. The identity of counselling psychology is strongly rooted in a relational stance and applied psychology, where attention to psychological formulation is given to improve psychological functioning and well-being. This article outlines a brief history of counselling psychology in the UK, the training process, credentialing and looks at some important challenges and future directions for counselling psychology in the UK. A proportion of the members from the British Psychological Society’s division of counselling psychology (DCoP, N = 148) took part in the study. Participants provided demographic, training, employment, workplace and career pathway information obtained through an online questionnaire distributed to all DCoP members. On the whole, DCoP members are working in a variety of areas within the UK and the findings of this article contribute to the international study comparing counselling psychology across the globe.

Why is Research Still Invisible in Further Education?

This article takes as its starting point earlier research reported by Geoffrey Elliott in 1996. That study found that research was consistantly marginalised in the FE sector, and identified a number of structural factors that contributed to this ‘invisibility’. This new study draws upon a small sample of lecturers who belong to a Further and Higher Education Early Years Partnership. Through the participants’ voices and perspectives, the authors identify continuing dissonance and issues of research marginalisation. The discussion also highlights contemporary educational discourse, with its predominant focus upon measurable value at the expense of values, as a key factor in sustaining a culture that is antithetic to thoughtful reflection and research. The authors identify the development of a ‘collaborative centralised’ research community as critical to an alternative possibility for research in further education.

Complexity theory and tourism policy research

This paper investigates applications of complexity theory in the social sphere and considers its potential contribution to enhance understanding of tourism policy making. Five concepts are identified to explore complex social circumstances and human interactions that influence policy. Social applications of complexity suggest a move towards localised and deeper studies to explore the dynamics of policy enactment in context. It suggests complexity theory might be used as a thinking tool to enable a more holistic approach to policy analysis and investigate policy in its context, considering interactions between different policies/programmes, and the implications of human agency.
